Be it known that I, HENRIK V. Loss, a citi zen of the United States, anda resident of the city and county of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inRiveting-h Iachines, of which the following is a specification.

My invention relates to improvements in riveting-machines; and theobjects of my invention are, first, to furnish a rivetingmachine thestake-frame and cylinder of which will be formed separately and whichmay be detachably secured together; second, to furnish in connectionwith the cylinder-c asting a guide for directing the outer end of thepiston or plunger, and, third, to furnish a means for convenientlycompensating the wear upon the piston or plunger-guide.

In the accompanying drawings, forming part of this specification, and inwhich similar letters of reference indicate similar parts throughout theseveral views, Figure 1 is a side elevation of the upper end of one legof the stake and a central longitudinal sectional elevation through thecylinder and connected parts of a hydraulic riveting-machine embodyingmy improvements; Fig. 2, a section of Fig. 1 on line 2 2; Fig. 3, an endelevation of Fig. 1 Fig. 4, a plan of one of the liners.

a is the upper end of the cylinder-carrying leg of the stake of ariveting-machine.

b is a casting forming a separate unit, in one end of which is formed acylinder 0, and the other or forward end of which forms or carries aguide for the outer end of the plunger d, which forms part of or iscarried by the piston p and which carries the riveting-tool e.

The casting 17 carries the piston p and all the other working parts ofthe machine, and this casting, with the parts that it carries, forms aunit which is secured to the leg at of the stake by bolts f. Upon therear end of the top of the leg a is an abutment g, against which therear end of the base of the casting b impinges when the casting issecured to the leg by the bolts The forward end it of the casting 6forms or carries a circular bearing for the outer end of the plunger (1,which is circular in crosssection, and while this bearing may be formeddirectly in the outer end of the casting I prefer to form it partly bythe casting and partly by a cap 1', which is secured to the casting bybolts and which may be removed to permit the insertion or removal of theplunger or which may be ad justed to compensate for wear by removing oneor more liners 7c, Figs. 2, 3, and 4, which are interposed on both sidesbetween the bottom of the cap 1' and the top of the part it of thecasting b. The form preferred for the cap t is best shown in Figs. 2 and3, and the form preferred for the liners is shown in Fig. 4. The linersare formed of thin sheets of metal and are preferably furnished withslots Z to permit them to slid be in past the bolts y.

m is a bushing of Babbitt or other suitable metal carried by the top ofthe part h of the casting bto form a smooth and easily-replaceablebearing for the bottom of the plunger (1. For convenience theriveting-tool a is carried upon the upper end of the front of theplunger d, and in operation the principal wear will take place betweenthe under side of the top of the cap i and the top of the plunger. Whenthis wear becomes serious, one or more of the liners 7c are removed, andthe nuts on the bolts are set up until the cap i again bears properly onthe plunger. It will be observed that the bolts j not only serve to holdthe cap i in place, but also act to hold the forward end of the Ushapedcasting b against the top of the stake-leg c.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a riveting-machine, in combination, astake-frame, a piston-carrying cyinder, a piston, a cylindrical plungersecured to and concentric with said piston, and a cylindrical guide forsaid plunger, said cylinder and guide forming together a separate unitadapted to be bolted to said stake-frame.

2. In a riveting-machine, in combination, a stake-frame, a substantiallyU shaped piece in one leg of which is formed a cylinder for thedriving-piston and in the other leg of which is formed a cylindricalguide for the plunger, said cylinder and guide being upon the samelongitudinal axis and said U-shaped piece being adapted to be bolted tosaid stake.

3. The combination in a riveting-machine of a substantially U-shapedframe in one end of which is formed a cylinder and the other end ofwhich carries the under part of a cylindrical plunger-guide, a'pistoncarried by said cylinder, a cylindrical plunger carried in. aXialalinement by said piston, said plunger passing over said guide, and acap secured to said guide under which the upper part of said plungerpasses.

4. The combination in a riveting-machine,

of a substantially U-shaped 'frame in one leg of which is formed acylinder and the other leg of which forms part of a plunger-guide, a capadapted to be bolted to said guide-leg to complete the plunger-guide, apiston working in said cylinder, a plunger working in said guide, andmeans for compensating the wear between said cap and plunger withoutdismantling said plunger-guide and cap.

5. The combination in a rivetinganachine, of a substantially U-shapedframe in one leg of which is formed a cylinder and the other leg ofwhich forms part of a cylindrical plunger-guide, a cap adapted to bebolted to said guide-leg to complete the plungenguide, a 1 pistonworking in said cylinder, a plunger of circular cross-section, in axialalinement with i said piston, working in said guide, and means I wherebythe wear between said cap and plunger may be compensated without dismanltling said plunger-guide and cap.
